Synopsis

#include <sys/scsi/scsi.h>

Interface Level

Solaris architecture specific (Solaris DDI).

Description

A scsi_hba_tran_t structure defines vectors that an HBA driver exports to SCSA interfaces so that HBA specific functions can be executed.

tran_hba_dip

dev_info pointer to the HBA supplying the scsi_hba_tran structure.

tran_hba_private

Private pointer which the HBA driver can use to refer to the device’s soft state structure.

tran_tgt_private

Private pointer which the HBA can use to refer to per-target specific data. This field may only be used when the SCSI_HBA_TRAN_CLONE flag is specified in scsi_hba_attach(9F) . In this case, the HBA driver must initialize this field in its tran_tgt_init(9E) entry point.

tran_sd

pointer to scsi_device(9S) structure if cloning; otherwise NULL .

tran_tgt_init

is the function entry allowing per-target HBA initialization, if necessary.

tran_tgt_probe

is the function entry allowing per-target scsi_probe(9F) customization, if necessary.

tran_tgt_free

is the function entry allowing per-target HBA deallocation, if necessary.

tran_start

is the function entry that starts a SCSI command execution on the HBA hardware.

tran_reset

is the function entry that resets a SCSI bus or target device.

tran_abort

is the function entry that aborts one SCSI command, or all pending SCSI commands.

tran_getcap

is the function entry that retrieves a SCSI capability.

tran_setcap

is the function entry that sets a SCSI capability.

tran_init_pkt

is the function entry that allocates a scsi_pkt structure.

tran_destroy_pkt

is the function entry that frees a scsi_pkt structure allocated by tran_init_pkt.

tran_dmafree

is the function entry that frees DMA resources which were previously allocated by tran_init_pkt.

tran_sync_pkt

synchronize data in pkt after a data transfer has been completed.

tran_reset_notify

is the function entry allowing a target to register a bus reset notification request with the HBA driver.
